In this problem, we are trying to find the range of function.
The range represents all the possible y-values of any function, which usually shows up the vertical values.
In this graph, we see some important details:
Notice the graph continues to move to the negative half of the graph in both directions. That means the y-value is going to be less than some value.
The dotted line shows the graph goes no higher than y = -3, but it can be equal to -3.
So, the range of our function is the second option, B:
[tex]y\leq-3[/tex]
